AFAIK Mandrill is similar to SendGrid that I use myself. This should allow you to create individual mails. The number of mails doesn't really matter.

As long as you don't use your own ISP you should be fine. These companies are professionals. Anything else is going to get you flagged as spam. Rather sooner than later.

The basics of sending an email is not complicated:

 socket1.address = "smtp.sendgrid.net"
 socket1.port = 587
 socket1.password = "xxx"
 socket1.username = "xxx" 'both come from sendgrid
 'now assemble your individual emails with from, to, body, attachments
 socket1.messages.append MailToCompany
 socket1.sendMail

This is from Xojo, I know in Filemaker it's a bit more complicated but the principle is the same.
